Nine more suspected drug dealers, most believed to have been peddling heroin, are facing charges after a bust Monday in Blair, Cambria and Bucks counties.

The suspected dealers were being served arrest warrants; seven were in Altoona, Johnstown and Oakford, Bucks County, and two are incarcerated, according to the state Bureau of Narcotics Investigation and Blair County Drug Task Force.

On Thursday, eight suspected heroin dealers thought to be involved in a Centre County drug ring were arrested and charged with various counts. Two additional suspects in the operation were still at large.

Monday’s bust wasn’t related to the State College ring, said BNI Regional Director Tony Sassano.

“The suspected dealers were part of a low-level operation,” Sassano said. “They were low-level street dealers within Blair County, primarily.”
